Allocapnia nivicola ( Fitch, 1847)

Notes

This species is commonly referred to as the Brook Snowfly ( Stark et al. 2012). The range of this species extends from New Brunswick, Nova Scotia, and Quebec southwest to Alabama and west to Illinois and Wisconsin ( Ross and Ricker 1971, DeWalt et al. 2024). Adult flight period dates for this common and widespread species extend from mid-February to mid-April (Fig. 7 ). In New York, this species is common and has been reported from small rocky streams at 7-545 m asl (Fig. 9 ) throughout the state (Fig. 11 b ).
